Yeah - it looks like two different colors to me as well. The blue ice color seems to be popular for the 2013s (by me anyway). Give your outback a good wash and compare it to another one with the same color on their lot.
Point out the difference and have them fix it.
Heck, compare it to the front factory bumper. If it matches, then fine. If it is different as the majority of us think it is, then re-do the entire job.
First car I ever painted had metallic flake paint with clearcoat over it from the factory. I had to mix the paint just right along with the metal flake just so.
The guy in the auto store told me that
I needed to know what I was doing to repaint portions of my car. I purchased everything and worked on it about three weeks. When I was done, it looked like a brand new car, one couldn't tell the difference between the OEM factory paint and the paint I applied, that was how well it matched. And, I didn't paint the entire car, just the hood, behind four wheels, lower doors, lower door jambs, etc. When I was done, the car looked brand new.
I learned that everything must be clean and there is a lot of sanding, buffing and polishing to get it right.
When I put my mind to something, I can do it, even if I need to improvise in certain things where some special tool is needed.
